DESTILASI SURYA MENGGUNAKAN ABSORBER PLAT SENG DAN TERPAL ( FLUROCARBON SHEET ) UNTUK MENGHASILKAN AIR TAWAR DAN GARAM

Abstract

Indonesia is the largest archipelagic country in the world with the number of islands as much as 13,466, Most of Indonesia is coastal area, where in that area lack of clean water. The effort for water supply is by utilizing the distillation of solar power, in this study the absorbent plate used for solar distillation devices is made of zinc plate and tarpaulin. This study aims to compare and determine the productivity performance of solar distillation apparatus using zinc plate absorbers by using the absorber from the tarpaulin. The working principle of solar radiation is converted into heat energy in the collector, the heat will be collected in the absorbent plate and heat the seawater in the basin with the cross-sectional area of 80 cm x 50 cm x 10 cm, the slope of the cover glass 30 °, And cover glass 2 slope, This research was conducted on April 12, 2017 until 29 April 2017 in open field beside Laboratory of Materials Engineering and Physical Metallurgy Department of Mechanical Engineering University of Bung Hatta Padang. From a study conducted with 6 liters of seawater used in testing a solar distillation device for a solar distillation apparatus using zinc plate absorbent plate produced 3726 ml of fresh water and a salt of 201.88 grams. While the solar distillation device using absorbent plate from the tarpaulin produces fresh water as much as 4820 ml and salt as much as 196,4 grams with an average intensity of 489,72 W/m² sun. This test is performed on the same and conditions.
